Introducing the Enduralube “A” Series Bearings: The World’s Most Reliable Bronze Bearing

Enduralube Graphite Plugged Bronze Bearings

National Bronze Mfg. Co. is proud to announce the addition of a new series of bearings to its Enduralube Self Lubricating Bearings line.

Enduralube bearings are known as the “world’s most reliable bronze bearing”.  They consist of a cast bronze alloy base metal, along with solid dry lubricant plugs machined and pressed throughout the contact are of the bearing.  This combination of strength and maintenance free use makes the Enduralube Bearings an ideal choice for many demanding applications



The Enduralube “A” Series bearings can be utilized where heavier than normal loads are required as well as in environments normally corrosive to bronze. They key to the load bearing and anti-corrosive properties of the “A” series is the use of an aluminum bronze alloy as the base metal.  When exposed to corrosive environments that aluminum bronze creates an aluminum oxide coating that further protects the metal.
